Make sure that injection of object elements continues to work in IE 6. Really hard to unit test this in a meanigful manner (the result is a visually broken plugin). Will need to be diligent about watching for this in the future. Fixes #5094.

Add .delegate() and .undelegate(). An alternative to using .live() which goes from a single root and filters by the specified selectors. Should be used like do: .delegate(td, hover, someFn);. Fixes #6005.
